Unruly
True, unfortunatly reality of today´s societey. When we went to fly in the 70´s as a Pax we had worn suit and tie and the Girls the Sunday dress...... look today. We have around one trouble maker in a month. Doesn´t matter if they smoke, argue, bringing plants on bord or just are up to get attention because they think they can. If they get too noisy then they can fly too... from the Pax-list if the problem starts during the bording.
We had recently another 30 min. delay because of taking two Pax off and looking for the bags. It would of no use if I would start to intervene from face to face and end up up punched. There are very "sensible" Security and Police Officers around who have been trained to handle it and do not hesitate to grap the moment to use the trained skills one to one and set the pace.
If it is during the flight we do not hesitate to land somewhere else and off load the person or group. Strictly obey the security thread to be removed. The costs born to that will be handed over, mostly a fruitless attempt, to the trouble causing Pax.
By the way I had unruly´s in First or Business Class as well during the middle of the night over the Pacific in the past, so not only Kettle.
